• Description: USB UART IC - Single chip USB to asynchronous serial data transfer interface
• Manufacturer: FTDI [Future Technology Devices International Ltd.]

9.5 Solder Reflow Profile
The FT232R is supplied in Pb free 28 LD SSOP and QFN-32 packages. The recommended solder reflow
profile for both package options is shown in Figure 9.5.
Figure 9.5 FT232R Solder Reflow Profile
The recommended values for the solder reflow profile are detailed in Table 9.1. Values are shown for both
a completely Pb free solder process (i.e. the FT232R is used with Pb free solder), and for a non-Pb free
solder process (i.e. the FT232R is used with non-Pb free solder).
